(2)

The deviation of each output from the OUT0 to OUT15 constant-current average. Deviation is calculated by the formula:

where n = 0 to 15.

(3)

Deviation of the OUT0 to OUT15 constant-current average from the ideal constant-current value. Deviation is calculated by the formula:

Ideal current is calculated by the formula:

(4)

Line regulation is calculated by the formula:

where n = 0 to 15.

(5)

Load regulation is calculated by the equation:

where n = 0 to 15.
